cooling issue

Sounds like you have a bad coolant temp sensor you have two its the bottom sensor with two wires going to it.So the fan doesn't come on when the temp gauge reaches about 3/4 on the gauge.Also if your a/c works does the fan come on with the a/c?

I haven't tried the air yet. When we bought the car it had no thermostat in it. I put one in but the fan doesn't come on.

So the fan doesn't come on at about 3/4 on the temp gauge?Or a little past it?Try the air and let me know if it works and fan comes on with the air.Really common for the coolant temp sensors to go bad.

The fan doesn't come on when the air is turned on.

Also we ran it to 3/4 and a little past and it still didn't come on.

Does the a/c clutch kick on when you turn the a/c on?If so and radiator fan doesn't come on then more then likely you have a bad fan motor.See if you have power and ground to the motor with the a/c clutch kicked in.The wire with a red tracer should have power and the solid black one is ground.If you doing then you have a bad fan motor.Let me know what you find.

The fan is hard wired on all the time, it works. It just doesn't turn off and on like it should. Also the compressor kicked on but the system needs charged.

If the fan motor works you most likely have a bad coolant temp sensor its the bottom sensor with two wires going to it.Its screwed into the head right below where the upper hose goes on.Also inspect the connector going to it if its corroded replace the connector also.The sensor is only 10 i wouldnt leave it hard wired not good for the engine to never getting fully warmed up.Alos with the sensor being bad it means the engine is running too rich.When the sensor gets bad enouhh the engine wont start it could surge die while driving etc.

Thanks, I will give this a try and keep you updated.

Cool keep me updated.
